Waste Water Solution in Taiwan

Southern Taiwan Science Park (STSP) pilot plant, Chia Nan University, Taiwan

An extensive pilot trial based on full-scale MBR membrane modules has been conducted by the Department of Environmental Engineering and Science, Chia Nan University, at an industrial site in Taiwan. The work included measurement of the sludge and foulant characteristics.

The 10 m³/d plant compromised a 10 m³ buffer tank followed by process and membrane tanks each having an 8.7 m³ working volume (and thus providing 42 h HRT). The plant was challenged with wastewater at 16-28˚C and generally between 800 and 12,000 mg/L COD concentration derived from combined pharmaceutical and septic tank effluent.

The MLSS concentration was increased from 6,00 to 12,000 over an initial operating period of 80 d, and was then operated at 12,000-17,000 mg/L solids concentration for a further 40 d. The viscosity was found to vary logarithmically with MLSS over the entire concentration range studied. At a mean SRT of 40 days and COD loading of 0.099-6.488 kgCOD/(m³.d).

Objectives

What they needed:

Convenient hydration to support high-traffic public areas
A sustainable solution to reduce reliance on single-use plastic water bottles
A hygienic and contactless dispenser
Integration with our partner City to Sea’s Refill app to help passengers find water stations on the go.

Our Drinking Water Solution

Our Max UV bottle filling station was the perfect choice for the station, thanks to UV technology and convenient contactless dispensing.

A bottle saving counter display helps users keep track of plastic bottles saved from landfill.
A fully customisable wrap to go with Network Rail’s branding and messaging to tell passengers they can get a free water refill.
UV Sterilisation kills 99.99% of bacteria and viruses within the water
Hygienic automatic touchless dispense

“We wanted to ensure we had a free water refill provision available to all our passengers at Bristol Temple Meads so we can be more sustainable in our refreshment offerings at the station and to remove the need for passengers to buy bottled water to stay hydrated. We’re delighted to have partnered with City to Sea to promote the benefits of reducing plastic pollution and to celebrate the refill revolution.”

Conclusion

By installing our bottle filling stations an estimated 150,000+ plastic bottles have been saved from waste. This has reduced Network Rail and Bristol Temple Meads environmental footprint along with helping them to meet their ESG and sustainability goals whilst also meeting the needs of the passenger in providing filtered, clean drinking water. This is a great example of a 360 partnership between Culligan, Network Rail and City to Sea as thousands of refills have been recorded through City to Sea’s Refill app and has helped passengers avoid single-use plastic.
